Hello from MrBillDoesMath!

Answer:

AB = (-7,5,-7)

Discussion:

The vector AB = B - A =

(-4, 7, 2)   -  (3, 2, 9)  =                      => subtract component-wise

(-4 -3, 7-2, 2-9) =

(-7,5,-7)

Thank you,

MrB

The vector for the line AB is ( -7i + 5j -7k ).

What is a vector?

A vector is a two-dimensional entity with both magnitude and direction. A vector can be visualized geometrically as a directed line segment.

Given points are A(3, 2, 9) and B(-4, 7, 2). The vector will be calculated as:-

AB = B - A = ( -4 - 3 , 7 - 2 , 2 - 9 )

AB = ( -7 , 5 , -7 )

Vector AB = -7i +5j-7k

Hence, the vector AB is (-7i +5j-7k).
